Aimed at medical researchers and doctors for use in clinical trials and drug tests, the unnamed wearable will not be widely available to consumers, Google told Bloomberg.

The gadget will allow medical professionals to keep track of user data, even when the wearer is at home or out on the town. It could also be worn by healthy patients in order to pick up on early signs of disease, Andy Conrad, head of Google's life sciences team, told Bloomberg.

"I envision a day, in 20 or 30 years, where physicians give it to all patients," he said. "Prevention means all the time."

For now, Google is testing the device and eyeing regulatory approvals. Trials are expected to start this summer, Bloomberg said. Google did not immediately respond to a request for comment.

Google has taken on a number of health-related endeavors. Last year, it announced plans for a smart contact lens that could measure glucose level in tears to calculate blood sugar levels in people with diabetes, among other things. Last summer, Google partnered with pharmaceutical giant Novartis to produce the lenses.
